What is Patriot Day?

Patrtiot Day, also referred to as 9/11 or September 11, is a day of observance in honor of those who died in the September 11, 2001 terrorist attacks on the World Trade Center in New York City and the Pentagon in Virginia as well those who died in the hijacked Flight 93 that crashed in Pennsylvania. September 11 was designated as Patriot Day in December 2011 by a joint resolution of the U.S. Congress.

How do people honor those who died on September 11, 2011?

Under the resolution, the U.S. President is asked to proclaim September 11 as Patriot Day each year and to request that all U.S. flags be flown at half-staff. Americans also observe a national moment of silence beginning at 8:46 a.m., Eastern Standard Time, the time that the first airplane flew into the World Trade Center.
